The following is the effect caught in 3 screenshots spaced a couple of seconds apart;

If Memtest86+ rules out a system RAM issue, and the same thing happens with different driver sets, and you try a different display cable, then yes I would say it is defective.

Ok so I've tried out the card on my friend's system and it works fine.

So I brought it home, tried these things;
different dvi cable
different pci-e slot
memtest86+ (pass)
updated drivers video card and motherboard

I can't think of anything else to do, any ideas?

What power supply did your friends computer have? That card requires a minimum 500watt PS.

Sounds like it could be a PS issue...will your friend let you use his power supply to check it out?

Filled an RA form, a week later the supplier offered to give me a refund.

That's 2 DOA powercolor 7950's I got in a row..

I'm staying away from PowerColor from now on.

I'd stick with Sapphire myself. I strayed from them this time with this XFX 7970 because it was on a three day sale, and was punished with card failure.
